ANTIVIBRATOR BURNER FOR INCANDESCENT GAS-LIGHTS- Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed January 27,1905. Serial No. 242,950.

To all whom, it may concern.-

Be it known that I, CHARLES PHILIPP EHMANN, a subject of the Grand Duke of Baden, and a resident of Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Antivibrator Burners for Incandescent Gas- Lights, of which the following is a specification.

This invention relates to antivibrator burners for incandescent gas-lights; and it consists in the hereinafter-described improvements thereon.

In antivibrator burners hitherto in use the entire burner has generally been supported in a frame by an arrangement of springs and the gas-nozzle connected to the gas-supply pipe by an india-rubber tube. This arrangement has little durability and cannot be produced at a low cost. In some cases the burner-head has been arranged to slide with its socket on the tube of the mixing-chamber and supported on a spring. ment cushions only the vertical shocks, but not the horizontal ones,which are most injurious to the mantles.

The object of this invention is -to remedy these defects in an efficient and inexpensive manner.

On the drawings appended hereunto, Figure 1 shows an outside view of one form of the improved antivibrator burner; Fig. 2, a modified construction of the same, and Fig. 3 a section of the socket and the mixing-tube.

According to this invention the lower part of the burner, comprising the mixing-chamber a, is provided with a mixing-tube 6, extending upward, as usual, into a socket 0, extending downward from the upper part or head (i of the burner which carries the mantle. The internal diameter of the socket c is made larger than the external diameter of the tube 5, as shown in section by Fig. 3, so that the burner-head can move both vertically and laterally with respect to the lower part a, which is fixed upon the "as-supply pipe. Preferably the upper part of the mixing-tube is tapered, as shown, which allows of a larger vibratory movement of the burner-head without enlargement of the diameter of the socket c, which must be kept within certain This arrange-.

limits to prevent an excessive influx of air. A helical spring e, loosely enveloping the mixing-chamber and socket a, is fixed upon the mixing-chamber preferably by being constricted at its lower end h, so as to embrace the chamber a, and is constricted in a similar manner at the top 9, so as to grip the socket (1 below the burner-head c, which spring takes the weight of the whole burner-head and mantle and forms an elastic support or cushion for the same against vertical as Well as lateral shocks. In an arrangement represented by Fig. l the entire spring cushions both lateral and vertical shocks or vibrations of the mixing-chamber screwed to the gassupply pipe, the socket I) being free to move both vertically and laterally with respect to the tube (1. Where the lateral shocks are considerable and less movement is desirable, the central part of the spring is also constricted, as shown at f, Fig. 2, so as to embrace the lower part of the socket b, without, however, gripping it, so that the socket can slide in the constricted coil. In this case the horizontal shocks will be cushioned mainly by the lower part of the helical spring below the constricted part f, while vertical shocks will be cushioned by the entire spring, and the concentric position of the socket with the mixing-tube is effectually secured.

I claim as my invention 1. In a burner for incandescent gas-lights the combination of a mixing-chamber having a mixing-tube extending upward the upper end of said tube being tapered, a burner-head having a socket extending downward and surrounding said mixin -tube and of larger internal diameter than the external diameter of the mixing-tube and ahelical spring loosely surrounding said mixing-chamber and socket and constricted at each end so as to embrace the mixing-chamber at its base and to grip the socket underneath said burner-head.

2. In a burner for incandescent gas-light the combination of a mixing-chamber having a mixing-tube extending upward, a burnerhead having a socket extending downward and surrounding said mixing-tube, said socket having an internal diameter larger than the external diameter of said mixing-tube, and a helical spring loosely surrounding said mix- JOO ing-chamber and socket, and constricted at In testimony whereof I have hereunto afboth ends and at an intervening point in such fixed my signature in the presence of two Wita manner as to embrace the said miXingnesses.
